The deslagging process is described in detail below: when the welding of the welding plate is completed through the stirring head 2, continuous pieces of welding slag are usually remained on two sides along the width direction of the welding line, because the welding slag is firmly connected with the welding plate and has a large quantity, the manual cleaning efficiency is low and the cleaning effect is poor, therefore, when the stirring head 2 moves leftwards to complete the welding, the collecting bin 4 simultaneously drives the supporting plate 401, the cleaning rod 402 and the collecting bin 406 to move leftwards, the cleaning rod 402 is driven to rotate through controlling the second motor 405, the cleaning rod 402 at the rear side is taken as an example for a detailed description, the cleaning rod 402 is driven to rotate anticlockwise by taking the top down as a reference, the scraping block 40201 is driven to rotate anticlockwise, the scraping block 40201 is driven to cut the root of the welding slag, the cleaning of the welding slag is realized, and because the collecting bin 4 is provided with the protruding part 4001, the protruding part 4001 is attached to the surface of the welding line, meanwhile, the welding slag is extruded outwards along the width direction of the welding line, namely, the welding slag is extruded to the front and rear sides respectively to prevent the welding slag from moving inwards during cutting, the cleaning rod 402 is attached to the welding slag, so that the cleaning effect is ensured, the cleaned welding slag enters the collecting bin 4 by the suction force generated by the air pump 7 during air suction, and is further conveyed into the collecting bin 406 by the air supply pipe 6, so as to finish the collection of the welding slag, on the basis, in order to prevent the welding slag from being conveyed to the air outlet bin 5 by the air supply pipe 6, the welding slag is intercepted by the filter screen 407, the welding slag is prevented from being conveyed to the air outlet bin 5 by the air supply pipe 6, so that the welding slag is difficult to collect, further, when the welding slag is cut, the second elastic piece 403 is in a compressed state, the cleaning rod 402 always extrudes the root of the welding slag by the second elastic piece 403, after the cutting of the welding slag is finished, the welding slag is separated from the welding plate, at the moment, the second elastic piece 403 is reset, the supporting plate 401 is pushed to move to the front side, and the cleaning rod 402 is further driven to move to the front side, thereby promote the welding slag and move forward to be convenient for collect the storehouse 4 and collect the welding slag, thereby improve the collection efficiency of welding slag, when clearance pole 402 contacted the welding slag once more, clearance pole 402 is blocked and is moved backward, and then drive backup pad 401 and move backward, thereby make second elastic component 403 pressurized shrink, realize clearance pole 402 reciprocating motion, further, when backup pad 401 moves backward, it gathers board 404 to drive and move backward, and then collect board 404 front side with the remaining welding slag of welding slag board surface through gathering board 404, when backup pad 401 moves forward, it moves forward to drive and gathers board 404, and then promote the welding slag and the burr that collect to move forward, be convenient for collect storehouse 4 and collect, simultaneously, because second motor 405 output and clearance pole 402 sliding connection, and the scraping piece 40201 is provided with upper and lower two-layer, both sides setting are the cambered surface around the bulge 4001, when clearance pole 402 moves forward, clearance pole 402 contacts with the cambered surface of bulge 4001, through the cambered surface guide, make pole 402 upwards move, and then drive scraping piece 01 upwards, and then the welding slag 40201 is torn by the welding slag is further received in the extrusion effect when being cut from the welding slag 40201 that is located upper layer, thereby the welding slag is further torn off.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
